Hi everybody ! When I buid my project in Keil Arm ver.4 , there are some warnings and errors :
stm32f4xx_gpio.c(130): warning: #223-D: function "assert_param" declared implicitly assert_param(IS_GPIO_ALL_PERIPH(GPIOx)); stm32f4xx_rcc.c(266): warning: #223-D: function "assert_param" declared implicitly assert_param(IS_RCC_HSE(RCC_HSE));
stm32f4xx_rcc.c(2106): error: #20: identifier "RCC_BDCR_LSEMOD" is undefined SET_BIT(RCC->BDCR, RCC_BDCR_LSEMOD);
I included files : #include <stm32f4xx.h> #include "stm32f4xx_gpio.h" #include "stm32f4xx_rcc.h"
So what is the reason making those ? And how can i resolve the problem ? Thank you !
